JFreeChart selectively render lines

Please see the the xy/timeseries chart I have posted here: http://imagebin.org/151195

How do I selectively render only the horizontal lines, and leave out the lines between the neighboring data points that don't have the same y value? Basically the result would be a series of horizontal lines?

You'll have to scan your data model to find the ordinate where dy/dx < ɛ, for some value of ɛ near zero. Of course, you'll have to scan past the initial flat part, and decide how to deal with a series that never rises above ɛ.

Once you know the desired ordinate, use setLowerBound() on your domain axis.
